aMidianBorn Content Addon - No Options During Install

I'm stuck on this step to install the Content Addon. It says to "Choose "Manual" at the installation prompt", however, I never see the prompt. The mod just installs with no dialog boxes.

I thought maybe the STEP instructions were out of date, but even the ReadMe file (AMB_ContentAddon_Installation directions.txt) within the mod says, "During installation, you can choose any of the texture options you want."

Any guidance is greatly appreciated.

Just to confirm, the filename I downloaded is: aMidianBorn - Content Addon-24909-1-9.7z

You called it, <faceplant>I should stop doing all this modding at 2am</faceplant> but I can't help myself, this modding for Skyrim is way to cool and I'm happy to say I'm new to Skyrim as well as modding it. Not to mention I'm missing work over it, well, missing isn't the right word. lol Thanks for putting up with the newb.
